Answer:
Marginal cost will increase.
Profit will increase.
Yes, the firm should increase production.
Explanation:
A perfectly competitive firm has marginal revenue equal to $4 and marginal cost equal to $2.
A firm in a perfectly competitive market is able to maximize its profit when it produces at the point where the marginal revenue earned and the marginal cost incurred are equal. Â
Since the marginal revenue is higher than the marginal cost, it means the firm can increase profit by increasing production. Â
When the firm will produce more its marginal cost will increase, at the point where marginal cost and marginal revenue become equal the firm will have maximum profit.
